Solvothermal synthesis a novel hemidirected 2-D (3,3)-net metal-organic framework [Pb(HIDC)]n based on the linkages of left- and right-hand helical chains

A novel 2-D hemidirected metal-organic framework [Pb(HIDC)]n (1, H3IDC = imidazole-4,5-dicarboxylic acid) has been hydrothermally synthesized and characterized by elemental analyses, IR, TGA, and X-ray single-crystal diffraction. Compound 1 is the first MOF based on Pb(II) and imidazole-4,5-dicarboxylic acid ligand. The 2-D (3,3)-net architecture with a rare (4 · 82) topology is built from alternately arranged left- and right-handed helical chains bridged by HIDC2− ligand.
